How co-op works
Up to six players survive successive specimen waves by balancing complementary Perks, weapons, medical tools, and armor. Teams choose where to hold out and weld doors to redirect enemies, then preserve enough firepower and healing to defeat the final boss.
About this game
Killing Floor throws up to six players into wave-based survival horror against relentless hordes of mutant specimens. Each round escalates in difficulty, demanding coordinated defense, shared resources, and smart positioning to survive until the final boss encounter. This is pure cooperative survival, not competitive play.

Players choose from multiple perks like Sharpshooter or Medic, each offering distinct loadouts and team roles. Between waves, teams scramble to scavenge weapons, restock ammo, and weld doors shut. Combat is tense and communication-heavy, especially when juggling crowd control, healing, and preserving limited firepower against faster, tougher enemies.
The game supports online co-op for up to six players with cross-platform multiplayer across Windows, Mac, and Linux. Sessions reward tactical teamwork under pressure, turning chaotic last stands into memorable moments when the squad barely scrapes through the final wave together.
